2Pripyat, Ukraine (Chernobyl Zone)

Pripyat, abandoned since the 1986 Chernobyl disaster, attracts adventurous travelers on guided tours. While hauntingly fascinating, it remains hazardous due to radiation hotspots and collapsing structures.

Entry is strictly controlled, and safety rules must be followed. The risks here are environmental rather than criminal, but they make Pripyat one of Europe’s most dangerous tourist sites.
